URL Fragment Anchors -- may be a Safari Question

Hi,

I'm a new beginner so, please forgive if I am somewhat imprecise...

I'm wanting to use fragment anchors in my pages. (I think that is the
right term for them). So my URL will be something like pmrs/1#id56.

I am using REST and resource style mapping.

My first question is will this work o.k.? I've tested it a tiny bit
and it seems o.k. but I'm worried that I may collied with the mapping
processing.

My real question is, with Safari, going to the same URL but different
fragment anchor, sends the request to the server and the whole page is
redrawn. With Firefox (on a Mac), that is not the case. The desired
effect happens: the page simply scrolls to the right place.

Is what Safari doing because I'm doing something wrong or is this just
how Safari does things?

Thank you,

BTW Rails really ROCKS!!!
